IMPROVEMENT lN HEATERS..

Specification forming part of Letters Patent NO. 199, 803, dated January 29, 1878; application filed December 8, 1877.

.To all 'whom 'it may concern:

Be it known that I, JOHN P.^DAU'1}H, of Reading, Pennsylvania, have invented. a new and useful Improvement in Heaters, of which the following is a specification:

The object of my invention is to construct a simple and economical heater having a larger air-heating capacity than, heaters of the ordinary construction.

In the accompanying drawing, Figure l is a Vertical section of my improved heater, Fig. 2, a transverse Vertical section, and Fig. 3 a sectional plan on the line 1 2. i

A is the outer casing of the heater, and is preferably of the oval form illustrated in Fig. 3. B is the top of the heater, and D is the base, in which are openings a for the-admission of cold air. Within the base is a casing,

Z), of the ash-chamber E, which extends out- Ward to the front of the casin g A, where there is an opening furnished with a suitable door and register. On the top of the ash-chamber is a grate, F, and above the latter is the casing d of the combustion-chamber H, the latter containin g a fire-pot, e, (shown by dotted 1ines,) and communicating at the top through pipes f f with the chamber I, and the latter With the Outlet-pipe J, communicating with the chimney. Above the base of the heater there are two chambers, M M, one 011 each side of the combustion-chamber, between which and each of the said chambers M Mthere is apassage, m, through which air from the base can pass upward into the interior of the casing A. Air from the base can also pass into each of ;the chambers M, and thence,through inclined 1', ,tubes P, which cross the combustion-chamber, Iinto the casing A. At the rear of the com- "f bustion-chamber there is a shield, q, so that a portion of the air from the base may pass up- 'ward near the rear'of the casing of the said combustion-chamber, and may be highly heat- I ed by contact therewith.

The air admitted to the chambers M M, passes rapidly therefrom through the inclined tubes D D, and there being exposed to the direct action of the products of combustion, a high degree of heat must be imparted to the air before it reaches the main hot-air chamber in the casing.

The volumes of air which take their courses through thepassages m 'mand tare also highly heated by contact with the casing of the combustion-chamber, and additional heat is imparted to the air within the casing A by the casing of the combustion-chamber, the pipes f, and the casing of the chamber I.

The upper portion of the casing A is provided With any desired number of branches, w, for receiving the ends of the distributingpipes. i

I claim as my invention- 1. The combination of the casing A,inc1osing a hot-air chamber, the closed chambers M near the bottom of the same, the combustionchamber H, and the tubes P, which extend diagonally through the combustion-chamber,

communicate at their lower ends with the chambers M, and at their upper ends with the hotair chamber, as specified.

2. The' combination of the casing A, combustion-chamber H, the tubes P, chambers M, shield q, and passages m and t, all 'substantially as specified. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. i JOHN P. DAUTH.
